SPECIFICATION forming part of Letters Patent No. 229,356, dated June 29,1880.

Application filed April 27, 1880. (ModeL) To all whom it may concern:

Be it known that LFRANK P. BARNEY, a

. to the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification.

, My invention has for its object improvements in the construction ofseparable buttons and studs; and it consists, first, in a novelconstruction-and arrangement of locking devices and theircombinationwith the button-sections; secondly, in the peculiar construction oflocking lever, all as fully described hereinafter,

and shown in the accompanying drawings, in which- Figure l is a verticaltransverse section of a separable button or stud constructed accordingto my invention. Fig. 2 is a top-plan view of the locking-section of thebutton. Fig. 3 is a like view of the same with the cap or covering plateremoved. Fig. 4 is a blank, from which the locking-levers are made,shown in perspective. Figs. 5 and 6 are like views, showing the severalsteps in forming said locking-lever and Fig. 7 is an isometrical view ofsaid finished locking-lever with its spring attached.

In the above drawings all the various figures are drawn on an enlargedscale, and similar letters of reference are employed to indicatecorresponding parts wherever such may occur.

A represents that section of the button or stud carrying a hollow stem,to, preferably of cylindrical shape, provided at its lower end with aflaring flange, to, having a flat upper engaging or looking face, a forthe engagement of the locking lever or levers.

Bis the locking-section of the button or stud, carrying the post 1),adapted to fit into the hollowpost (t. This section B is composed of thebase-plate b, carrying the post b, an annular flange or rim, b and aperforated cap or covering plate, I), through which projects the postI), and into which enters the post a, said parts forming a casing forthe reception of the locking devices, which I will now describe.

0 O are two locking-levers having an extension, 0, that serves as apush-rod, a projection or arm, 0, that serves to support one end of theactuatingspring, and an upturned lip or flange, 0 having the hook ornose 0 that serves to engage the flange a of the hollow stem a, and saidflange 0 also serves as an abutment for the free end of theactuatingspring. These levers are placed in the casing B of the sectionB with the extensions or pushrods 0 projecting through the slits orslots 1), formed on opposite sides in the rim 1) of said casing, asshown in Fig. 3.

Any desired form of spring may beemployed. l prefer, however, to employa coiled spring, i), one end of which is supported by the arm 0 of thelever C, while the free end of said spring abuts against the flange c ofsaid lever when in position in the casing, as shown by Fig. 3. It willbe seen that by this arrangement the actuating-spring D is made to exertits power upon the levers O in two directions simultaneously-first, inthe direction of the axis of said levers through the arm or support 0,and, secondly, in a direction at right angles to said lever-axis orlaterally, which is necessary to hold the levers in properpositionrelatively to each other, as well as to the post and hollowstem, as it is evident that were the spring D to exert its power in thedirection of the lever-axis for the locking, of said levers to thehollow stem and post only, their displacement laterally wouldnecessarily follow andmaterially interfere with or completely destroytheir function.

Bymeans of the lateral pressure of the spring D the levers are heldagainst each. other, and their push-rods and bearing-flanges formbearings for their mutual support and proper operation, while thispeculiar locking device, owing to its compactness and simplicity, may beemployed on buttons or studs of very small size. These levers U arestruck up from sheet metal into blanks F, having the form shown in Fig.4., and being composed of a segmental body, f provided on its innerforward edge with a lip or nose, 0 of an arm, f, an enlarged part, f,and the nicked or reduced part f. To. form the lever G from this blankthe arm f, enlarged part f, and the outer orhook end, f, are first bentat right angles to the segmental body f as shown in Fig. 5, to form thelocking and bearing flange 0 0 above described. The part f, with its armf, is then doubled upon itself at the notched or reduced part f and thearm f is bent to conform, or nearly to conform, to the segmental body fas shown by Fig. 6, to form the push-rod or extension 0 and thesupporting-arm c for the actuating-spring above set forth, and, finally,the spring D is applied or attached to said arm a, as shown in Fig. 7,when the lever, with its actuating-sprin g, is ready to be placed intoposition in the casing 13, as shown in Fig. 3.

It will be understood that I do not limit myself to the exactconfiguration of button hereinbefore described, and shown in thedrawings, as buttons or studs of any desired shape may be employed; nordo I desire to limit myself to the exclusive use of the form oflocking-lever as I have described it, and shown it in the drawings, asit is evident that any other suitable form of lever adapted to beactuated by the spring in two directions, as described, may be employed.

I do, however, not desire to claim, broadly, the COIllbll'lzttlOll of aspring with a lockinglever when said spring is arranged to exert itspower in the direction of the axis of the lever and at right anglesthereto simultaneously, as I am aware that springs arranged to exerttheir power in this manner have been previously employed.

Having now described my invention, what I claim is- 1. The combination,with the section A and its hollow stem, provided with the flaringengaging-flange a (o of the section B, its post b, the locking-levers O,terminating at one end in a push-rod and at the other in an abutment, 0provided with the engaging lip or nose 0 and the actuating-springs D,having one end connected with said levers upon one side of the post andtheir free ends made to bear upon the lever-abutments on the oppositeside of the post, substantially as described, and arranged to operate asset forth.

2. The combination, with the section A and its hollow stem, of thesection B, its casin g or body I) b If, the post I), the locking-leversO, terminating at one end in a push-rod and at the other in avertically-projecting abutment having an engaging nose or lip, 0 andproyided with the projecting arm or bearing 0,

and the actuating coiled springs D, having one end supported by saidlever-bearing 0 upon one side of the post and their free ends made tobear upon the abutments on the opposite side of the post, substantiallyas described, and constructed and arranged to operate as set forth.

3. A locking-lever for separable buttons, having an extension, 0, toform a push-rod, an arm, 0, to support a spring, a bearing-flange, 0provided With a locking lip or nose, c and an intermediate segmentalbody, substantially as described, for the purpose specified.

4. The herein-described blank for lockinglevers, struck up from sheetmetal, and consisting of the segmental body f having the lip or nose 0the arm f, the enlarged part f, and the nicks or recesses fsubstantially as shown and described, and for the purpose specified.

In testimony whereof I afix my signatnre in presence of two witnesses.

FRANK P. BARNEY.
